      Description

      The issue is:

      • type is a required field for TCounter with enum type TUnit
      • Some readers (e.g. Java) that encounter an unknown enum value replace it it with null, then throw an exception because it is a required field

      This means that the workflow for adding a new TUnit is basically broken, since we can't add a unit in Impala then update readers later.

      I think we should switch to TIME_NS then reconsider the workflow here.
